Re: [Discuss-gnuradio] uhd_two_tone_loopback.grc example (Cindy Zhang)

The device is B200. It says the maximum sampling rate it can deliver is above 60M. Any other thoughts on this problem?

Hi Cindy Zhang,

I think it's your device that can not deliver 50M synchronously to the UHD. If possible up to the performance of your device.    Best regards

However, when I increase the sampling rate to 50M, I start to  get printouts on the screen: "UUU...", and it is very hard to stop the  running example. Besides, when it runs at 500K sampling_rate, no printouts  on the screen. Therefore, it is very easy to stop the application at 500K.  I got similar results for other applications written by myself.    What could be the reason that causes the printouts at higher sampling_rate?  Is there a solution for this problem? As I understand, 50M sampling_rate  should be acceptable for my device.    Thanks in advance.  -------------- next part --------------  An HTML attachment was scrubbed...
